IMPROVEMENT IN BEARINGS FOR SHAFT-HANGERS.

Specification forming part of Letters Patent No. 196,505, dated October23, 1877; application filed September 12, 1877.

To all whom it may concern:

Be it known that I, GUSTAV ALDOPH HEIN- RIOH'VOLLRATH, of the city ofAltona, Germany, have invented an Improvement in Bearings for Shafts andPivots; and I do hereby declare that the following is a full, clear,and. exact description of the same, reference being had to theaccompanying drawing, forming part of this specification.

The object of the invention is to supply a simple and advantageousbearing for shafts, pivots, and other transmitters of motion.

The invention will be sufficiently illustrated by a description of it asapplied to a vertical hanger for ordinary line-shafting. Figure 1 in thedrawing is a side view of such a hanger comprising my improvement, andFig. 2 is a vertical section of the same on the line 0: as in Fig. 1.

A is the hanger, which has formed in its lower part an opening, B, forthe reception of the box 0. Said opening is preferably made circular inform, as shown in Fig. 1. Said hanger may also have a slot, D, formed init for the insertion of the shaft, as hereinafter specified; but this isnot necessary -in. any case where the shaft or pivot may be insertedendwise, as in hangers for the ends of shafting. Said slot D is formedin the lower part of the hanger, to allow the entrance of the shaft orpivot into the opening B; but the said slot may be formed in any otherrelation with the said opening. Thus, for horizontal bracket-bearings,the said slot may be made either on the upper side or on the lower side,or midway between they said,

sides.

Said box 0 has formed on its under side two convex projections, c 0,preferably separated by a distance of about sixty degrees of itscircumference, and when inserted in the opening B it is held-in place bya set-screw, E, which engages,preferably,a countersunk recess formed inthe outer surface of said box.

To strengthen the slotted part of the hanger, and prevent its spreadingby the wedge-like act-ion of the projections c onthe inclined sides ofthe opening B, I fit and attach to the hanger a clamping-cover, F, whichis held attached to the hanger by screws G.

The slot D and clamping-cover F are only necessary for hanging the shaftin its bearings, which is accomplished as follows: The boxes 0 havingbeen slipped on the shaft, the shaft is passed through the slot D, andthe clamping-covers F are attached to the hangers. The boxes 0 are thenslid along the shaft and brought'into their proper positions in theopenings B, and fastened in place by the setscrews E.

This method of hanging secures great facil-.

2. The combination, with a support having v an opening, B, for thereception of a box, 0, provided with projections c, and a slot, 1),which allows the entrance sidewise of the shaft or pivot, of theclamping-cap F, fitted and at tached to said hanger,. substantially asand for the purpose set forth.
